Replacement for ThinkPad X131e and X140e

Verify model number and original part before

Check the sticker on your existing battery for the Lenovo part numbers listed above or the FRU codes 0A36290 and 0A36292. Confirm that your laptop outputs 11.1V, as some variants ship with different voltages. The smart control chip manages charging, but only when the host recognises the correct cell configuration.

Black 6-cell housing with integrated protection

The enclosure matches the original footprint and latch points so it seats flush in the battery bay. Built-in safeguards guard against short circuit, overheat and overload during daily charge cycles. A one-year warranty covers defects in materials and workmanship.
